ARCOS 625焊丝ERNICRMO-3焊丝NIFIL 625 is a solid MIG-filled wire of type S Ni 6625 / ER NiCrMo-3 depositing a transfer metal Ni-22Cr9Mo3.5Nb. Suitable for use with inert protective gases. It is used for welding alloys based on Cr-Mo-Nichel highly corrosion resistant, such as alloy 625, alloy 825 and similar alloys. Also suitable for corrosion-resistant molybdenum steels e.g. 7%Mo, such as X1NiCrMoCuN25-20-7 and tenacity steels nickel. In sulphur-free atmospheres, the input metal does not have a shear in sulphur-free atmospheres. instead it can be used <500oC. Present thermal expansion coefficient between austenitic and ferritic steels, for which it is also suitable for joining austenitic (dissimilar) ferrite steels at operating temperatures; or Post-welding heat treatment >300oC. It is also used for steel plating. It's very resilient. tensocorrosion and vaiolation in the presence of phosphoric acid, organic acids, sea water and environmentspollutants. Cryogenic Tenacity Up to -196oC. At higher temperatures there is a limited carbon diffusion in the intake metal that avoids the presence of infrared carbides in the welding interface of dissimilar joints.
